You can distribute the redistributable assemblies of VintaSoft Barcode .NET SDK as part of your application only if you have got a license for the SDK.

The files (DLLs and JavaScript files), which may be distributed as part of your application, are listed in paragraph 4.6 of the license agreement.

DLLs do not contain COM components and registry modification is not necessary. In most cases, DLLs must be placed in the same folder as the assembly that references it. Make sure that the version of DLLs you distribute is the version your assembly was compiled with.
